SILO.

Specification of Letters Patent.

Patented Sept. 5, 1916.

Application filed November 19,1915. Serial No. 62,353.

T 0 all whom it may concern Be it known that I, HATTIE M. JONES, a citizen of the United States, residing at Cassopolis, in the county of Cass and State 1 of Michigan, have invented certain new and useful Improvements in Silos; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in silos, and its primary object is the provision of a silo made up of blocks or slabs of concrete provided with interlocking side edges and overlapping and interlocking ends, the formation of the blocks or slabs being such that the weight upon the blocks or slabs of a course will not tend to separate the blocks or slabs of that course.

With the above and other objects in view, the invention consists in the construction of the block or slab hereinafter fully described and claimed, and illustrated in the accompanying drawing, wherein,

Figure 1 is a view in side elevation of a silo made up of blocks, or slabs, constructed in accordance with my invention, Fig. 2 is a horizontal section view taken on the plane indicated by the line 22 of Fig.1, and looking in the direction indicated by the arrows, and Fig. 3 is a detail plan view of one of the blocks or slabs.

Referring to the drawing by reference numerals, 1 designates the concrete blocks or slabs which are used to form the silo and which are provided with vertical side edges. Each slab 1 is provided at its ends with reduced and longitudinally projecting extensions 2, which have horizontal outer edges and inwardly and laterally inclined side edges. Horizontal shoulder-s 3 are located at the end edges of the slabs 1 on opposite sides of the extensions 2, and extend outwardly from the inner ends of the inclined side edges of the extensions 2. One vertical side edge of each slab 1 is provided with a groove 4 and the other vertical side edge is provided with a tongue or tenon 5. One inclined edge of each extension 2 is provided with a groove 4 and the other inclined edge is provided with a tongue or tenon 5.

The blocks or slabs 1 are curved transversely, and when the slabs or blocks are interlocked, by the tongues and grooves they form a circular inclosure which is practically water tight and air tight. The blocks or slabs 1 interlock and break joints as shown, and the projections 2 overlap as shown. Strong metal bands 6 extend around the completed silo at the overlapping projections 2. The bands 6 are connected together by means of bolts 7 which extend through the outwardly turned terminal ends 7 of the bands. The silo is provided with a door frame that consists of channel irons 8 which are spaced apart by cross bars 9. Braces 10 are connected to the channel irons 8 and serve as ladder rungs. Special concrete blocks, not shown, may be provided for the door sections. Any suitable concrete base 12 and any suitable metal or other cover 13 may be employed.

In constructing a silo, the slabs or blocks 1 are laid in horizontal courses, the vertical 'edges of the slabs interlocking. The end edges of the extensions 2 of each course are located in the same horizontal plane, and the extensions provide a plurality of recesses in which fit the extensions of the slabs of the next highest course which greatly fa cilitates the assembling of the slabs of said next highest course, and which causes the slabs of each course to be so laid as to break joints vertically.

The horizontal end edges of the lower extensions 2 of one course rest upon the upper horizontal shoulders 3 of the slabs of the next lowest course, and the horizontal shoulders of said first named courserest upon the horizontal end edges of the extensions 2 of said next lowest course. It will thus be seen that the upper horizontal shoulders 3 of the blocks or slabs 1, and the horizontal end edges of the upper extensions 2 of the blocks or slabs of each course support the weight of the blocks or slabs in the course or courses above it, whereby no weight, which would tend to separate the blocks or slabs, is placed upon the inclined side edges of the extensions 2.

From the foregoing it will be obvious that a silo made in accordance with this invention will be strong, durable and efficient, and that it can be readily and quickly built by unskilled labor. It should also be apparent that the silo would be practically air tight, and it may be utilized as a tank or bin for the storage of grain.

Various changes may be made in the details of construction without departing from the spirit and scope of the invention as defined in the claims.

Having thus fully described my invention, What I claim is:

1. The hereindescribed silo made up of a plurality of concrete slabs, each slab comprising a body having vertical side edges, reduced and longitudinally extending projections formed on the end edges of the body, said extensions having horizontal outer end edges and inwardly and laterally inclined side edges, and horizontal shoulders formed on the ends of the body, said shoulders extending outwardly from the inner ends of said inclined side edges of the extensions.

2. The hereindescribed silo made up of a plurality of concrete slabs, each slab comprising a body having vertical side edges,

Copies of this patent may be obtained for reduced and longitudinally extending projections formed on the end edges of the body, said extensions having horizontal outer end edges and inwardly and laterally inclined side edges, and horizontal shoulders formed on the ends of the body, said shoulders extending outwardly from the inner ends of said inclined side edges of the extensions, one of the side edges of the body being provided with a tongue and the other with a groove, and one of said inclined side edges of each of said extensions being provided With a tongue and the other with a groove.

In testimony whereof I afiix my signature in presence of two witnesses.
